API Access Unavailable after phone verification attempt - China (+86), OTP SMS never arrives

Hello NVIDIA Support Team,

I cannot complete phone verification on build.nvidia.com. After attempting the SMS OTP, my account now shows “API Access Unavailable - Please contact support to verify your account access” and I am unable to generate a NIM API key.

Account details:

  • Registered email: 10239259@qq.com
  • NVIDIA org: 1080071975090217
  • Region: China (+86)
  • Phone number tried: a mainland China number (real-name personal mobile, not VoIP / virtual / disposable)

Problem:
The page accepts my number and opens the OTP entry screen. It says to wait up to 90 seconds, but no SMS ever arrives. I also tried “Resend code” and waited much longer than 90 seconds.

Already tried:

  • Enabled international SMS receiving with my carrier
  • Checked spam / blocked message folders
  • Incognito browser, cleared cache and cookies
  • Retried at different hours over several days
  • Confirmed the number is active and receives other international SMS normally

My account already has the required entitlements:

  • NVIDIA Developer Program member (isRdpMember: true)
  • NIM Dev, Omniverse Dev, NVIDIA Dev subscriptions active

Could you please manually verify my account, or let me know what else I need to provide? I have also emailed help@build.nvidia.com as instructed in the pinned post and can provide the full phone number and a screenshot there.

Thank you for your help.
